Obviously this is a mod for minecraft and not Real Life Simulator but I want to point out that rainbow eucalyptus bark is only very slightly blue and the wood isn't blue at all. Imo it does create a very jarring look in the game that isn't "nice".

Maybe it being very blue is intentional but if it isn't I want to point this out

Repeat of #258 ... It is an artistic decision. If you don't like it, you can turn off generation of the rainbow rainforest biome in the config...
